Before you get started you’ll need:

Step 1: Download and install GCMM

Go to the GCMM page to download the latest version of GCMM. Inside, there is a folder with the same name as the zip file. Inside that folder, there is a “gamecube” folder. Inside of that folder, there is a .dol file. Copy that file your homebrew storage device, usually an SD card.

Step 2: Copy the SD Remix Lite save file

On your homebrew storage device, usually an SD card, create a folder at the root of your SD card called “MCBACKUP” in all capital letters.

If you haven’t already, download the latest version of SD Remix Lite for your version of SSBM. You can get it at the SD Remix Lite Download page. It should be a zip file with a .gci file inside.

Copy the .gci file from the SD Remix Lite zip into the “MCBACKUP” folder you just created.

Step 3: Run GCMM on your GameCube

Using whatever homebrew device you use, navigate to the GCMM dol and run it.

Note: If you are using the SD Media Launcher, we recommend you put the SD Media Launcher in Slot B and your memory card in Slot A, as GCMM tends to not work the other way around.

When it starts, it may ask you which slot you’ve put the SD Gecko in. If you are using the SD Media Launcher, this is the slot that the SD Media Launcher is in. If you’ve put the SD Media Launcher in slot B, press “B” to indicate so (press “A” if it is in slot A). You should now be at the main menu, where it says “Choose your mode”.

Step Optional: Backup your existing save file

If you already have an existing SSBM save file, installing SD Remix Lite to your memory card will overwrite that save file. Fortunately, you can backup your save file to restore it later. If you want to make a backup of it, you may do so at this time.

To do the backup, choose “Backup”, which is the “Y” button.

It will ask you which slot to read from. Pick whichever slot your memory card is currently in.

It will now have a list of save files currently on your memory card. From the list, pick the one that says “01-GALE-SuperSmashBros0110290334” (or “01-GALP-SuperSmashBros0110290334” for our PALs in parts the world), by highlighting it and pressing “A”. It will tell you when it has finished backing up the save file.

Step 4: Restore the SD Remix Lite save file onto your memory card

We now want to choose “Restore”, which is the “X” button.

It now asks you to choose a memory card slot to restore to. Choose whichever slot has the memory card in it.

There should be at least one save file called “01-GALE-SuperSmashBros0110290334” (or “01-GALP-SuperSmashBros0110290334” for our PALs in parts the world). If you’ve made a backup, there will be multiple with the same name. You can double check the dates of each save file, but the SD Remix Lite save file is likely to be the last one listed of that name. Highlight that one and press “A” to start restoring.

If you have an SSBM save file on the memory card already, it will prompt whether you want to overwrite your existing save file. Press B to confirm. It will then ask are you sure you want to overwrite it. Press “Z” to confirm again.

When it is done restoring, it should give you a message saying it is done. Congrats, you now have SD Remix Lite on your memory card! If your SD Remix Lite is behaving oddly, such as crashing or some of the expected changes not appearing, move on the Troubleshooting below.

Troubleshooting

Some players have had issues with GCMM not correctly writing to certain types of memory cards, generating corrupt SSBM saves that either don’t work at all or only partially work. This mostly affects off-brand memory cards, especially ones that have been through a lot of use. If you’re running into issues with your memory card, you might want to try your other memory cards, if you have some. The best memory cards tend to be the big brand memory cards, such as Nintendo, MadCats, and Nyko. I’ve also personally tested that this KMD memory card seems to work (and it’s pretty cheap), but that might be because I tested it while it was brand new.
